It is used to bear mainly the radial and also certain axial load. The outer ring of such bearing is of spherical shape, hence, it has center adjusting function. When the axis is bended or inclined upon force exercised on it, the bearing still functions normally if the relative inclination of the centerline of the inner ring is thin 1~25. This bearing has greater loading capacity, but lower rotation speed limit.
